PIN SAFETY-LOCK.

Specification of Letters Patent.

Application filed March 8, 1911.

Patented Jan. 23,1912.

Serial No. 613,026.

To all whom it may concern:

Be it known that I, SOIHUS J. E. VVIL- HJELM, a citizen of Denmark, anda resident of Brooklyn, Kings county, New York, have invented certainnew and useful Improvements in Pin Safety-Locks, of which the followingis a specification.

This invention relates to improvements in safety looks or guards forjewelry and like articles. The invention, however, is not limited tosuch use but may be found practical, useful and applicable in connectionwith other articles and for other purposes.

The detailed construction of my invention is fully set forth in thefollowing specification while reference is had to the accompanyingdrawing in which- Figures 1 and 2 are side views of a brooch pinembodying my invention and showing the pin in closed and open positionsrespectively. Fig. 3 is a sectional view on line 83 of Fig. 1. Fig. 4 isa view of the blank which forms one element of the invention. Figs. 5and 6 are views of a modified form of the invention showing two steps inthe process of making it.

Referring to Figs. 1 to 3 the numeral 8 represents a brooch or likearticle and 9 is the pin for securing the brooch in the usual manner tothe garment. The two principal objects of the invention are to provide asafety locking device for locking the pin firmly against accidental oruntimely opening and to form the locking means in such a manner that thepoint of the pin is contained within the lock to prevent injury. In thepresent instance I accomplish these objects by the following means.Referring to Fig. 4, 10 is a blank stampedor made to form a base 11, twoperforated pivot lugs 12, 12 and a pin guide 13. It may be made of anysuitable metal and the base 11 is secured to the back of the brooch bysolder or otherwise. 14 is a spring locking member freely rotatable onthe pivot pin 15 which is inserted in the pivot lugs 12 as will beunderstood. The spring '14 is provided with an aperture 16, see Fig. 3,to permit the spring to pass over the pin point 17 of the brooch 9. Thespring 14 is an expansion spring and has the tendency to throw the freeend 18 outwardly or to the right in the drawing.

The operation of the device is simple. When the brooch pin is looked asin Fig. 1 it passes through the aperture 16 in the spring 14 and thepoint 17 is contained within said spring thereby preventing injury.Further, the brooch pin cannot be opened without moving the springendwise of the brooch or to the right and this cannot be to be locked itis laid down in the forked portion in the guide piece, which registerswith the opening 16 and the spring lock is then snapped up over the pinpoint 17 as in Fig. 1, whereby the free end 18 is forced outward andthus automatically locks the pin which cannot be unlocked except bymanual operation.

The guide piece is not essential to the successful operation of thedevice but helps to prevent sidewise movement of the pin 9, and toposition the latter with respect to the opening 16 in the spring 14.

In Figs. 5 and 6 is disclosed a device for securing the end of a watchchain or other article. In this instance there is formed a blank 20having a ring 21 to which a watch chain may be attached. 22 is the pinportion and 23, 23 the pivot lugs. The portion 24 forms a base similarto the base 11 above. After the lugs 23 are bent at right angles to thebase portion 24 the pivot pin 15 and the spring 14 is inserted asbefore, after which the blank is given a quarter turn as at 25 to bringthe lock in proper position under the pin 22. The operation for lockingand unlocking the latter is the same as above described. This device maybe used at the edge of a vest where either the pin is looked through abutton hole or the pin may be shaped to easily penetrate the garment.The distance between the 'lock and the ring 21 depends somewhat upon howthe device is to be used. The pin 22 may be very short and springy ifdesired.

From the foregoing it will be seen that I have invented a pin safetylock of very simple and practical construct-ion, and which may be usedfor purposes entirely'different from those disclosed without materiallychanging the construction or departing from the spirit of the invention.

I have found that this device may be made at little cost and works well.

The device may be either made to be attached to a piece of jewelryalready made or itmay be incorporated in the article while the latter isbeing constructed.

I claim:

1.- The combination of a brooch, a pin for securing the same, a springadapted to lock the said pin, said spring being bent in the form of anupwardly curved loop and provided with an aperture to admit the point ofthe said pin to project within the said formed loop and having a freeend portion abutting the said brooch at right angles thereto forpreventing accidental removal of the said pin, the said spring beingadapted to be moved away from the point of the pin to release thelatter.

2. The combination of a brooch, a pin for securing the same, a lockingspring adapted to engage the said pin to lock the same and having a freeend portion adapt- .ed to engage the said brooch to prevent accidentalremoval of the pin, said free end portion when locked standing at rightangles to the brooch and in front of the said pin to protect it againstinjury and adapted to be bent in under the point of the pin to releasethe latter.

3. The combination with a brooch and a pin for securing the same, of alocking means for said pin comprising a spring pivoted at its one end tothe said brooch, the body of the spring being bent to form an upwardlycurved loop and provided with an aperture for the passage of the pin tosecure the latter, the other free end of the spring being adapted toabut the brooch at right angles to prevent accidental removal of theCopies of this patent may be obtained for five cents each, by addressingthe Commissioner of Patents, Washington, D. G.
